Use scene graph shown in Fig. 1, the angle performing the method that the embodiment of the present invention provides with terminal 101 is
Example, sees Fig. 3, and the method flow that the embodiment of the present invention provides includes:
Step 301: obtain the target Mobile Country Code MCC of terminal current location.
Terminal obtains the Mobile Country Code MCC of its current location, can be the shifting obtaining its present position district
Dynamic national code, with this Mobile Country Code MCC for target Mobile Country Code MCC.Wherein in a lane place, mobile
It is not required to make location updating when platform moves process.There is the Mobile Country Code MCC of correspondence each lane place.General one
The corresponding Mobile Country Code MCC in individual area, in an area, Mobile Country Code MCC is the most identical, and such as China is big
The Mobile Country Code MCC in land is 460, and the Mobile Country Code MCC of Germany is 262.One of them area can have multiple
Lane place, the Mobile Country Code MCC in the diverse location district belonging to same area is identical.
Terminal can use various ways to obtain the Mobile Country Code MCC of current location, and such as, terminal receives base station
Sending the broadcast message of coming, this broadcast message includes the network information, this network information includes that target moves
National code, so, terminal just gets the target Mobile Country Code MCC of current location.Or, terminal also may be used
From the equipment of other detection Mobile Country Code MCCs, get target Mobile Country Code MCC, and user is directly to this
Terminal input Mobile Country Code MCC is also feasible, and the embodiment of the present invention obtains target Mobile Country Code MCC to terminal
Concrete form do not constitute restriction.
Such as, user goes to Germany from China's Mainland, the mobile phone PLMN to be carried out of the use ESIM of user
Selecting operation, now, this mobile phone receives the broadcast message of base station, and user mobile phone obtains from broadcast message
Getting Mobile Country Code MCC is 262.
Step 302: when selecting RPLMN failure, it is judged that target Mobile Country Code MCC and EHPLMN's
Whether Mobile Country Code MCC mates, if coupling, then performs step 308, otherwise, performs step 303.
Wherein, EHPLMN preserved by the ESIM card of terminal.This EHPLMN can with only one of which,
Multiple PLMN can also be included.RPLMN is terminal PLMN before shutdown last time or off-grid in registration.
The network registered as the last time because of RPLMN is general for being successfully accessed rate and turn-on time
It is optimum.When terminal selects RPLMN failure, the PLMN of GC group connector registration already out last time
Service area, now terminal selects other PLMN.Wherein RPLMN can be saved in the internal memory of terminal
In.
First target Mobile Country Code MCC is mated by terminal with the Mobile Country Code MCC of EHPLMN,
EHPLMN is equivalence local plmn, it is provided that the operator of EHPIMN and the IMSI (English of ESIM
Literary composition full name: International Mobile Subscriber Identification Number, Chinese full name: state
Border mobile identification number) corresponding operator is same operator, if target Mobile Country Code MCC with
The Mobile Country Code MCC of EHPLMN matches, and terminal may be still at the clothes of operator corresponding for its IMSI
In the range of business, so, now terminal performs step 308.If IMSI is virtual operator is supplied to user
, be Incumbent because of provide PLMN service, then corresponding for IMSI operator can be to this void
Intend the Incumbent of carrier supplying service.
Step 303: judge whether the Mobile Country Code MCC of target Mobile Country Code MCC and HPLMN mates, if
Join, then perform step 308, otherwise, perform step 304.
Terminal preserves HPLMN, and this HPLMN can be saved on ESIM, and HPLMN is that user is whole
The PLMN of the ESIM ownership of end, if target Mobile Country Code MCC and the mobile national code-phase of HPLMN
Join, terminal may in the service area of HPLMN, so, now, terminal perform step 308.
Such as, the Mobile Country Code MCC of the present position-region that terminal gets is 262, with the ESIM of this terminal
The operator of signing is the AA virtual operator of China, and this AA virtual operator buys industry from China Mobile
Business, thus on the ESIM of this terminal, preserve EHPLMN and HPLMN that China Mobile provides, in
The Mobile Country Code MCC of EHPIMN and HPLMN that state moves is 460, and terminal detects present position-region
Mobile Country Code MCC 262 different from Mobile Country Code MCC 460, then terminal may be in international roaming, then eventually
OPLMN on end detection ESIM.
Being appreciated that in the embodiment that the present invention has, terminal is likely not to have and preserves EHPIMN, now,
Target Mobile Country Code MCC is directly mated by terminal with the Mobile Country Code MCC of HPIMN.That is, target is moved
The Mobile Country Code MCC of dynamic national code and EHPLMN carries out the step mated not necessarily.
I.e., in some embodiments of the invention, target is moved by terminal according to the preservation situation of EHPLMN
The Mobile Country Code MCC of the PLMN that dynamic national code and terminal preserve mates, if terminal is preserved
The Mobile Country Code MCC of EHPLMN, the most first coupling target Mobile Country Code MCC and the mobile national of EHPLMN
Code；If terminal does not preserves EHPLMN, then terminal is by target Mobile Country Code MCC and the mobile state of HPLMN
Family's code mates.Wherein, PLMN can be saved in ESIM by terminal.
Step 304: judge whether the Mobile Country Code MCC of target Mobile Country Code MCC and OPLMN mates, if
Join, then perform step 305, otherwise, perform step 307.
When the Mobile Country Code MCC of target Mobile Country Code MCC and HPLMN does not mates and this target Mobile Country Code MCC
When not mating with the Mobile Country Code MCC of EHPLMN, according to target Mobile Country Code MCC and the movement of OPLMN
National code selects target PLMN.
Wherein, OPLMN be write ESIM default area terminal ESIM estimate log in network,
Default area is not construed as limiting by the embodiment of the present invention, and it is special to be that Germany, the U.S. or Hong Kong etc. are assigned
The area of Mobile Country Code MCC, can be by a Mobile Country Code MCC uniquely identified area.Write ESIM's is pre-
If area can have one can also have multiple, it is also possible to no write, do not write then step 304 and judge to lose
Losing, the embodiment of the present invention does not constitute restriction to this.Area when default area with the IMSI ownership of ESIM
Time different, then this OPLMN presetting area of write ESIM card is roaming network.
If this OPLMN record has the IMSI of registered network expected from Current resource, i.e. this terminal ESIM
Be expected to the network logged in current location, then terminal may select this OPLMN and registers.OPLMN
Can be write by operator.OPLMN can preserve with tabular form in the terminal.This OPLMN
May refer to determine the PLMN of operator, this appointment operator can be the fortune corresponding with the IMSI of ESIM
Battalion business signs the operator of cooperation agreement, so, when terminal enters the service area of this appointment operator,
The PLMN of this appointment operator can be connected.
OPLMN in ESIM is controlled knowable, and the PLMN resource of write is than traditional SIM card more
Easily controllable.
The Mobile Country Code MCC of target Mobile Country Code MCC and HPLMN do not mate and this target Mobile Country Code MCC and
The Mobile Country Code MCC of EHPLMN does not mates, and represents this terminal and has been not at the IMSI ownership of its ESIM
Carrier service in the range of, now can attempt obtain with home-operator have the appointment of service agreement to transport
The service of battalion business, such terminal just can get corresponding business service.
Step 305: select the OPLMN matched.
When the Mobile Country Code MCC of target Mobile Country Code MCC and OPLMN matches, then terminal is likely located at
In the service area of OPLMN, and this OPLMN can be the operation that can provide signing service to this terminal
The PLMN that business provides.Thus terminal is when carrying out selecting PLMN operation, directly selects Mobile Country Code MCC
The OPLMN matched with target Mobile Country Code MCC, such terminal selects the success rate of PLMN to obtain
Improve.If the OPLMN matched is multiple, terminal may select one of them OPLMN, such as signal
Good OPLMN.
If terminal searches network planning still according to 3GPP standard, select PLMN, the most first select EHPLMN
Or HPLMN, the most now terminal will network selection failure, and then terminal and then selects other PLMN, such as
UPLMN or OPLMN, so, the trial that network selection is failed will waste the time of user.When terminal institute
In the case of the physical location at place exists substantial amounts of network, note net can be the longest with the time obtaining service.When
In the case of the card resource downloaded supports roaming on a large scale, the time can be longer.
And the coupling that the terminal of the embodiment of the present invention is by Mobile Country Code MCC, it is judged that disabled PLMN,
Such as, when Mobile Country Code MCC and the Mobile Country Code MCC of HPLMN of target Mobile Country Code MCC and EHPLMN
When not mating, terminal can determine whether out that this EHPLMN and HPLMN is the most unavailable, thus the most right
EHPLMN and HPLMN selects, it is to avoid what network selection was unsuccessfully brought loses time.Now, because of
OPLMN record is the PLMN that can register when being in present position-region of terminal, i.e. the mobile state of terminal
The PLMN that when family's code is the Mobile Country Code MCC of present position-region, terminal can be registered, thus, terminal selects
During the OPLMN that Mobile Country Code MCC and target Mobile Country Code MCC mate, the successful probability of terminal network selection will
Improve, which reduce the time searching net, registered network of terminal, convenient for users to use.
Such as, it is 262 that terminal gets the Mobile Country Code MCC of present position-region, and terminal reads preservation on it
OPLMN list, detects, has Mobile Country Code MCC and the present position-region of PLMN in OPLMN list
Mobile Country Code MCC identical, be all 262, record because of this OPLMN is that the ESIM of terminal is registrable
PLMN, thus terminal can attempt the OPLMN that selection Mobile Country Code MCC matches, if this OPLMN
For multiple, terminal can select one of them according to preset rules from the plurality of OPLMN matched
OPLMN, such as, select signal intensity maximum.
Step 306: judge whether normally get service on OPLMN, if can not, then perform step
Rapid 307.
After terminal chooses the OPLMN matched, can the OPLMN of this selection get
Normal service does not understands.Therefore, after selecting OPLMN, can terminal detection from this OPLMN
Get normal service, i.e. can communicate normally, the business such as networking.
Step 307: select to specify the network of PLMN list.
Wherein, it is intended that PLMN list is the list that signal quality reaches the PLMN of preset value, and it is permissible
Including a PLMN, it is also possible to include multiple PLMN.
If terminal can not obtain normal service from the OPLMN matched, then can be normal for user
Use terminal communicates, and terminal can re-start the selection of PLMN, now can select to specify
The network of PLMN list.Or the mobile national as EHPLMN, HPLMN and OPLMN three
When code and target Mobile Country Code MCC do not mate, if terminal selects EHPLMN, HPLMN and OPLMN
All will be failed, so now terminal directly selects the network specifying PLMN list.Wherein, this appointment
PLMN can be the terminal currently detected signal intensity PLMN more than preset value, and it eliminates
EHPLMN, HPLMN and OPLMN on ESIM, it is intended that PLMN list can include one
PLMN, it is also possible to include multiple PLMN.So, terminal can avoid selection to select during network selection
Select EHPLMN, HPLMN and OPLMN of failure, and directly select the net specifying PLMN list
Network, thus improve the speed of network selection.
Specify PLMN list, such as, can be that received signal code power RSCP value is more than-84dBm
PLMN, thus when endpoint registration to this PLMN, communication quality is unaffected.
Be appreciated that although step 306 can be that user's network selection provides preferably service, so that user's choosing
Select the PLMN that signal is good, but step 306 is not necessarily, can not hold in certain embodiments
Row step 306.
Step 308: search network planning then select target PLMN according to presetting.
Wherein this is preset and searches the cell reselection PLMN that the agreement that network planning can be then aforesaid 3GPP specifies
Selecting sequence, it is also possible to be terminal or the rule of selection PLMN that user pre-sets.
The target Mobile Country Code MCC of present position-region and the Mobile Country Code MCC of EHPLMN or HPLMN
Join, then terminal can also get the service of home-operator of IMSI, now terminal can first search for it
Near whether have the signal of EHPLMN and HPLMN, if having, selecting these PLMN, otherwise continuing
The selecting sequence of the cell reselection PLMN that the agreement of execution 3GPP specifies.
The terminal of the embodiment of the present invention can include UPLMN, it is also possible to do not include UPLMN, preferably
Terminal does not has the situation of UPLMN, can edit because UPLMN is user, and controllability is poor,
Terminal may judge that target Mobile Country Code MCC is identical with the Mobile Country Code MCC of UPLMN, but carries out
During the selection of UPIMN, but select less than corresponding UPLMN.So, in the embodiment that the present invention has
In, close the UPLMN write-in functions of ESIM card.
In some embodiments of the invention, select RPLMN failure after, terminal can the most first than
The most identical with the Mobile Country Code MCC of OPLMN compared with target Mobile Country Code MCC, if identical, then terminal is direct
Select the OPLMN that matches, and do not perform by target Mobile Country Code MCC respectively with the movement of EHPLMN
The Mobile Country Code MCC of national code and HPLMN carries out the step mated, and such scheme falls within the present invention
Scope, be also when terminal network selection by coupling Mobile Country Code MCC first determine optional PLMN, choosing
Select the PLMN of this coupling, thus decrease and search the net time.But the preferably embodiment shown in Fig. 3, because being somebody's turn to do
Network selection flow process shown in embodiment is the national code of the first PLMN that coupling note net success rate is big, so can enter
One step reduces searches the net time.
In sum, the method selecting network of the embodiment of the present invention, pre-by the coupling of Mobile Country Code MCC
First select the PLMN that may succeed in registration, decrease the time searching net, in embodiments of the present invention, if
Select RPLMN failure, then by target Mobile Country Code MCC respectively with the Mobile Country Code MCC of EHPLMN,
The Mobile Country Code MCC of HPLMN mates, and the probability roamed in international regions because of terminal is less than this area
Communication, thus target Mobile Country Code MCC respectively with Mobile Country Code MCC, the movement of HPLMN of EHPLMN
The success rate of country code matches is higher, so, by target Mobile Country Code MCC respectively with the movement of EHPLMN
National code, the Mobile Country Code MCC of HPLMN first mate, and contribute to minimizing and search the net time.And first select
RPLMN is because the probability of RPLMN chosen successfully is relatively big, so can also contribute to reduce terminal and searches net
Time.If target Mobile Country Code MCC respectively with the Mobile Country Code MCC of EHPLMN, the mobile state of HPLMN
All it fails to match for family's code, then the Mobile Country Code MCC of target Mobile Country Code MCC and OPLMN is carried out by terminal
Joining, if the match is successful, then terminal may get the service of the OPLMN matched, and terminal is successfully noted
The probability of the OPLMN that volume matches is very big, so, now terminal selects the OPLMN matched.
If the Mobile Country Code MCC of target Mobile Country Code MCC and EHPLM, HPLMN and OPLMN does not mates,
Then, terminal selects to specify the network of PLMN list, because by the coupling of Mobile Country Code MCC, terminal is in advance
Judge that EHPLMN and HPLMN and OPLMN does not the most provide service in current location, so terminal
Directly selecting other PLMN, this also can improve searches net spee, decreases terminal equally and searches the time of net.
Embodiments of the invention are not limited to when roaming use, and can make in any scene of terminal network selection
With, first select RPLMN, i.e. first select being chosen to prominent PLMN, it is ensured that search
The speed of net.After selecting RPLMN failure, compare the mobile national of the PLMN preserved in ESIM
Code and the Mobile Country Code MCC of terminal current location, prejudge out optional PLMN, then judge this
PLMN select, thus eliminate in network selection can the failed PLMN of network selection, directly select choosing
It is selected to high-power PLMN, improves and search net spee.
